Appendix A contains illustration of suffix designation
A. 
Similar sounding names are considered to be duplication regardless of spelling, affix and/or prefix.
B. 
No duplication of names is permitted within the projected service area of the county, a United States Post Office or of local public agencies such as fire and police departments.
C. 
Previous duplications (See § 279-24C).
A. 
A continuous street, or one proposed to be continuous, should bear the same name throughout, even though it changes directions. If it is interrupted by a channel, freeway, railroad, etc., and eventual connection is not probable, the segments shall bear different names.
B. 
Loop or U-shaped streets which would create duplication of house numbers require two names, the change to occur at a knuckle or sharp turn, may be excluded from the above in the event such an identifiable break point does not exist. In these cases, the utilization of an appropriate affix as determined by the Community Development Department may be allowed.
C. 
No separate name is to be used for a cul-de-sac that provides street frontage for three or less lots or dwelling units. The name shall be the same as that of the intersecting street. Where there is a series of long and short cul-de-sacs, however, all should have separate names.
D. 
At the time that two roads/streets are connected, the county shall initiate the naming of the road/street pursuant to the § 279-20C of this Ordinance.
